Siri, Alexa and Gemini for Seniors: Easy Voice Commands
How to use Siri, Alexa and Google Gemini in plain steps: how to wake each one, 25 handy things to say, how to set reminders and calls, privacy settings, and what not to ask a voice assistant.
Quick answer: A voice assistant lets you do things just by talking. On an iPhone, say "Siri" (or "Hey Siri") or press and hold the side button. On an Android phone, say "Hey Google" or press and hold the power button, and Gemini answers. With an Amazon Echo speaker, just say "Alexa". Then ask in everyday words, like "Set a timer for 20 minutes" or "Call my daughter." All three are free to start, and you don't need to download anything.
Voice assistants are the easiest kind of AI to start with. There's nothing to type and no small buttons to find. They're good at quick jobs: timers, reminders, phone calls, the weather, spelling a word, or playing the radio. This guide shows how to set up each one, what to say, and the few settings worth changing.
Which assistant do you have?
| If you have... | Your assistant | How to wake it |
|---|---|---|
| An iPhone or iPad | Siri | Say "Siri" or "Hey Siri", or press and hold the side (or top) button |
| An Android phone, like a Samsung Galaxy or Google Pixel | Google Gemini | Say "Hey Google", or press and hold the power button |
| An Amazon Echo speaker or Echo Show | Alexa (or the newer Alexa+) | Say "Alexa" |
| A Google Nest speaker or display | Google Assistant, or Gemini for Home if you've been invited to switch | Say "Hey Google" |
You only need one. If you have an iPhone and an Echo, many people use Siri when out and about and Alexa in the kitchen.
Siri on an iPhone or iPad
Turn it on: open Settings, tap Siri, and make sure Siri is on. Choose whether you want to wake it by saying "Siri" or "Hey Siri". You'll be asked to say a few phrases so it learns your voice.
Use it: say "Siri" and then your request, or press and hold the side button and talk. You don't need to pause or speak like a robot. Talk the way you would to a person.
Rather type than talk? Go to Settings → Accessibility → Siri and turn on Type to Siri. Handy in a quiet waiting room.
The new Siri AI (beta). On newer iPhones (iPhone 15 Pro or later, and every iPhone 16 or newer) with iOS 27, you can try a smarter Siri that holds a real back-and-forth conversation and can look things up on the web. Go to Settings → Siri → Try Siri AI (Beta) and follow the steps. You may be put on a short waitlist. It comes with its own Siri app that keeps your conversations, and there are daily usage limits. In late October 2026 it works in English, French, Japanese, Korean, Portuguese and Spanish, and isn't available in the EU yet (per Apple's support and news pages). Older iPhones keep the regular Siri, which still does everything on this page.
Using an iPad? The steps are the same. See how to use AI on an iPad for bigger text and read-aloud tips.
Gemini on an Android phone
In September 2026, Google replaced Google Assistant with Gemini on Android phones and tablets. If you used to say "Hey Google," it still works. Gemini now answers.
Turn it on: open the Gemini app (or the Google app) and follow the setup. To use your voice hands-free, turn on "Hey Google" & Voice Match in the Gemini app's settings.
Use it: say "Hey Google", or press and hold the power button (on some phones, swipe up from a bottom corner). Ask your question out loud.
For reminders, Gemini saves them in Google Tasks. The first time, it may ask you to connect Google Workspace, and Gemini's activity setting (Keep Activity) needs to be on. Open the Google Tasks app afterward to check the time is right. On newer Samsung Galaxy phones, reminders can go into Samsung Reminder instead.
For a real conversation, tap Live in the Gemini app and chat out loud. You can interrupt it, just like a person. Gemini Live is free on phones.
Alexa on an Amazon Echo
Set it up: plug in the Echo, download the Amazon Alexa app on your phone, sign in with your Amazon account, and follow the steps to connect the Echo to your Wi-Fi. A family member can do this with you in about ten minutes.
Use it: say "Alexa", wait for the blue light, and ask. On an Echo Show, answers also appear on the screen in big print.
Alexa or Alexa+? Alexa+ is Amazon's newer, chattier version. It's included free with Amazon Prime, or $19.99 a month without Prime (Prime itself is $14.99 a month). It works on most newer Echo devices. The regular Alexa is still free and handles timers, reminders, calls, music and the weather just fine. To try Alexa+ with Prime, say "Alexa, upgrade to Alexa+."
25 easy things to say
These work on Siri, Gemini and Alexa, so just start with the wake word ("Siri," "Hey Google" or "Alexa").
| Job | What to say |
|---|---|
| Timers | "Set a timer for 20 minutes." "How much time is left?" |
| Alarms | "Wake me up at 7 a.m. tomorrow." |
| Reminders | "Remind me every day at 8 a.m. to take my morning pills." "Remind me at 3 p.m. to call the pharmacy." |
| Calls | "Call my daughter." "Call Dr. Patel's office." (The name must be saved in your contacts.) |
| Messages | "Text Tom: I'm running 10 minutes late." "Read my new messages." |
| Weather | "Do I need an umbrella today?" "What's the weather this weekend?" |
| Calendar | "What's on my calendar tomorrow?" "Add lunch with Ann on Friday at noon." |
| Lists | "Add milk and eggs to my shopping list." "What's on my shopping list?" |
| Spelling and words | "How do you spell 'rhythm'?" "What does 'deductible' mean?" |
| Quick math | "What's 18% of 64 dollars?" "How many cups in a quart?" |
| Music and radio | "Play some Frank Sinatra." "Play the news." |
| Phone help (Siri and Gemini) | "Turn on the flashlight." "Turn the volume up." "Make the text bigger." |
| Directions (Siri and Gemini) | "How do I get to the library?" "How long to drive to Mom's house?" |
| Explain something | "Explain what a Medicare Advantage plan is, in simple words." |
Tips that make it work better:
- Say the whole thing in one go. "Remind me on Thursday at 2 p.m. to call the plumber" works better than three short tries.
- Check what it heard. Your phone shows the words on screen. If it got it wrong, just say it again a little slower.
- Save names in your contacts with how you'd say them ("Mom," "Dr. Patel"), so "Call Mom" works every time.
- Ask it to repeat. "Say that again" or "Slower, please" both work.

When a voice assistant is not the right tool
Voice assistants are great for quick jobs. For longer ones, like explaining a confusing letter, writing a careful email or planning a trip, a chat app such as ChatGPT or Gemini (where you can read and re-read the answer) is easier. See the best AI app for seniors, ranked by ease, or start with our 25 easy ChatGPT prompts for seniors.
Scammers sometimes put fake "support" numbers online, and an assistant may read one out. For your bank, Medicare, Amazon or any company, use the number on the back of your card, on your statement, or on the company's own website. And if a caller sounds like a grandchild in trouble, hang up and call them back on the number you know. Here's how to set up a family safe word for AI voice scams.
Emergencies
- iPhone: saying "Siri, call 911" places the call. Also set up Emergency SOS (in Settings) and your Medical ID (in the Health app), so responders can see your medicines and contacts.
- Android: open the Phone app and dial 911, or ask Gemini to call it. Most Android phones also have Emergency SOS under Settings → Safety & emergency, which can call for help when you press the power button several times quickly.
- Alexa: by default, an Echo can't call 911. Amazon sells Alexa Emergency Assist (U.S. only, $5.99 a month, or $59 a year with Prime and $79 a year without, as of October 2026). Say "Alexa, call for help" and a trained agent can send police, fire or an ambulance and alert your family. It isn't a 911 service. Many people prefer a medical alert button or simply keeping the phone nearby.
Privacy settings worth two minutes
Voice assistants keep a record of what you ask. You can look at it and delete it.
- Siri: go to Settings → Siri → Siri & Dictation History and tap Delete Siri & Dictation History. With the new Siri app, you can set conversations to delete after 30 days. Full steps: how to delete Siri history on iPhone.
- Alexa: in the Alexa app, tap More → Alexa Privacy → Review Alexa History, where you can delete one entry or Delete All History. Full steps: how to delete Alexa history. Under Manage Your Alexa Data, you can choose to have recordings deleted after 3 or 18 months, or not saved at all. (Saying "Alexa, delete what I just said" works on the regular Alexa once you turn on deletion by voice, but not on Alexa+.)
- Gemini: your chats are saved under Gemini's Keep Activity setting (it used to be called Gemini Apps Activity). Our guide to deleting Gemini and Google AI Mode history shows how to delete them or set auto-delete. Note that Gemini reminders need Keep Activity turned on. Google AI Mode searches are saved separately, in your Search history: here's how to delete AI Mode chat history.
- Echo speakers have a microphone off button on top. Press it (the light turns red) when you'd like Alexa not to listen.
And the golden rule: don't say passwords, bank or card numbers, or your Social Security or Medicare number out loud to any assistant. See what not to share with AI.
Helping a parent set one up
Set it up on their phone or speaker, with them holding it. Save the family's names in their contacts, set one daily reminder together, and practice three requests until they feel easy: a timer, the weather, and calling you. Write the three phrases on a card by the speaker. Our 30-minute guide to helping a parent use AI safely has more ideas.
FAQ
What is the easiest voice assistant for seniors? The one that comes with what you already have: Siri on an iPhone, Gemini on an Android phone, or Alexa on an Amazon Echo. For hands-free help around the house, an Echo is the easiest because you just talk across the room.
How do I turn on "Hey Siri"? Open Settings, tap Siri, and choose to listen for "Siri" or "Hey Siri." Follow the steps to teach it your voice. You can also press and hold the side button to talk to Siri anytime.
Is Google Assistant gone on Android phones? Yes. In September 2026, Google replaced Google Assistant with Gemini on Android phones and tablets. You can still say "Hey Google" or press and hold the power button, and Gemini answers. Google Nest speakers are moving to Gemini for Home separately.
Is Alexa free? Yes. Regular Alexa on an Echo is free. The newer Alexa+ is free with Amazon Prime, or $19.99 a month without it. Alexa Emergency Assist is an optional paid add-on.
